CORPORATION OF PENNSYLVANIA.

HAULAGE SYSTEM.

Application filed September 9, 1908.

To all whom it may concern:

Be it known that 1, PAUL A. DEGENER, residing at Pittsburg, in the county of Allegheny and State of Pennsylvania, a citizen of the United States, have invented or discovered certain new and useful Improvements in Haulage Systems, of which improvements the following is a specification.

The invention described herein relates to certain improvements in the manner of sup porting draft chains, such for example as that known in the art as saw tooth chains employed in car transfer apparatus for tipples, mines etc.

The invention is hereinafter more fully described and claimed.

In the accompanying drawings fori'ning a part of this specification Figure 1 is a side elevation showing a portion of a hauling chain and my improved guides therefor; F ig. 2 is a side elevation showing adjacent sections of the guides on an enlarged scale, and Fig. 3 is a plan view partially in section of the parts shown in Fig. 2.

In the operation of mines, coal tipples, etc, it is customary to employ a constantly moving chain for the operation of the cars. The cars as they approach the portion of the track along which the chain operates have a considerable momentum generally faster than the rate of movement of the chain so that for some distance will move at a higher rate than the chain, and means must be provided to engage the cars about the time when their rate of movement becomes equal to that of the chain. It is preferred to em ploy a chain having teeth or projections on its links preferably one on each alternate link. The teeth are so constructed as to engage a part of the car or a lug or projection thereon and also to permit the car passing over them when the speed of the car is greater than that of the chain, as the car passes over them, the teeth and portions of the chain adjacent thereto will be deflected or forced down and do not materially affect the movement of the car.

Heretofore the chain has been placed under a guiding tension so as to permit the car when its speed is the greater, to depress and pass over the teeth which are normally held to engage the car when the speed of the latter becomes less than that of the chain.

In the construction shown the haulage Specification of Letters Patent.

Patented Nov. 24, 1908.

Serial No. 452,236.

chain 1 is provided with a series of sawteeth projections 2, the projections or teeth being straight on the edges in the direction of movement of the chain and having their rear edges sloping or inclined so when the lug on the car strikes this inclined surface, it will tend to force the chain downward and permit the car-projection or lug to pass over the teeth. This chain is supported by a guide consisting of a series of sections 3 capable of being depressed when the lug on the car strikes the teeth of the chain. Each of these sections 3 is pivotally connected adjacent to one end, preferably, its rear end to an arm 4 of a bent lever 5 which is pivotally mounted in a supporting frame 6 as clearly shown in the several figures. The outer end of the lever 5 is provided with a weight 7 adapted to counterbalance the section 3 and hold it in normal position. The downward movement of the weight is limited in any suitable manner, preferably by means of stops 8 secured by straps 9 to the supporting sections 6. The rear end of each section is pivotally connected to the front end of the next succeeding section as clearly shown in Figs. 1 and 2. The length of these sections is immaterial and may be adapted to the purposes for which it is to be used. hen a car passes along in a direction of the arrow (1 a lug or projection thereon will strike one or more teeth of the chain in succession and in so doing will depress the section immediately beneath such tooth or teeth. The depression of one section will also tend to depress, but in a lesser degree, the adjacent sections both in the front and in the rear. Of course the amount of movement of a section will depend upon the position of the tooth when struck by the car. Vhen the tooth is between the pivotal point 5 of the lever and the front end of the supporting section, the latter will turn about the pivot 0 connecting it with the next adjacent section in the rear and there will be comparatively little movement of such rear section. W hen however the tooth when struck by the car is in the rear of the pivotal point I), the section supporting such tooth will tend to turn on the pivotal point connecting it with its lever, and will impart some considerable tipping movement also to the next section in the rear.

It is characteristic of my improved sup port that the guide and chain are given a sinuous movement by the passage of the car along the chain. 7

t Will be readily understood by those skilled in the art, that the number or construction of the teeth carried by the chain are immaterial, but it is preferred that the teeth should be closely adjacent to each other so as to avoid imparting any great shock or jar to the car When a tooth engages the same.

I claim herein as my invention:

1. In a haulage system, the combination of a chain having teeth or projections and a sinuously yielding guide therefor.

2. In a haulage system the combination of a chain having teeth or projections, a guide formed of sections for supporting the chain and yielding means for supporting the sections.

In a haulage system, the combination of a chain having teeth or projections a guide formed of pivotally connected sections and yielding means supporting such sections.

l. In a haulage system, the combination of a chain having teeth or projections, a guide formed of pivotally connected sections, and Weighted levers pivotally connected to the sections and forming yielding supports therefor.

In testimony whereof, I have hereunto set my hand.
